Probably a stupid question and if it's already been answered I apologise but I couldn't find an answer! Can you put a contract 2G SIM card in a contract 3G phone, i.e. from Orange for example? Any help please to victoriamcneile@mac.com or just post here! Many thanks and sorry for being a thicky blonde female!

Thats so funny. My mate works in a three store in OZ. They told him that if he puts a 3g sim into a 2g mob it would destroy the mob. I could not understand how that would happen. I wonder if he did that would the mob pick up the 2g network that three roams with in oz?

I heard that if you put a Three sim in a 2G phone it will work for a while but then get blocked. This is becuase it starts using the O2 network and Three gets charged for this.

It appears that the capabilities and restrictions of 2G/3G sim cards are dependent on the networks and their available technology.

Here in the Philippines, mobile 3G is still in its trial stage, but the leading mobile 3G network (Smart) has somehow made all the old 2G sims forward-compatible: Available mobile 3G services will work as long as your UMTS unit is capable of handling them. No special 3G sim cards are sold (yet).
